Hi, I would like to know what bullets you guys use in your 6BR 1:8 twist rifles...

I want to order bullets but there is so many options. :confused:

I also would like to hear what you use as powder and the seating depth with the bullet you use in relation with the lands.

BTW I have Varget, 4895 and Benchmark powder on hand.


Just for the record, my rifle is a Tikka 595 Master Sporter with a brand new 28″ long 1:8 Krieger ( Heavy Palma profile ).

105gr bullet of your choice, if your barrel is new start at 29gr of Varget, CCI 450 primers. Bullet jump depending on brand, should be close to one ragged hole:) VV N140 Is just as good as Varget with the heavy bullets and burns cooler. If you have a good chamber they are boringly easy to find a good load.

As above. I have 2, one likes 105 hybrid over H4895, the other 107 smk over Varget.

Of all my rifles, the 6mmbr with 107 smk was the easiest to load for - I loaded 28-30gr, in 0.3, and they were all under 1/2MOA 3 shot at 200. Had to go out to 300 to see the diff. 29.8 Varget was the winner, 20 off.
 
From what I can read on the net and from your imputs, the best/most popular options are the 105 Lapua Scenar, 105 Berger and 107 SMK.

I always liked everything made by Lapua and I think I'm gonna listen to Jerry about the .236" bore of my barrel, so I'm gonna try the 105 Scenar first.

I will also begin with Varget powder and we'll see...

Thanks for the input guys !
 
For those who use Lapua 105, what distance from the lands do you seat the bullets ?

I know each rifles are different but that can give me an idea...
 
So I received the Lapua bullets today.

Had a hard time finding where the bullet don't hit the lands.

Is an OAL of 2.327" sounds right ???

I thought the bullet will protude a little bit more...

Of course I will have to remove .015-.020" to that dimension...

I re-did the test today.

I removed the firing pin mechanism and the ejector from the bolt just to be sure to don't have any tension from those mechanism.

Finaly, the OAL where the bullets meet the lands is 2.315" and I'm 100% positive its the correct length.

Favorite 6BR Accuracy Loads for 80gr to 108gr Bullets
Favorite Recipes

There is no “screamer” load that works in every rifle. Some barrels prefer Bergers, others Sierras or Lapuas. Powder lots vary considerably–this will affect your max velocity and tune. Your barrel twist will also dictate the bullets you can run–you’ll need an 8-twist to run the heavy (105-108 grain bullets). The Berger 95 VLDs normally demand a 1:9″ or faster. The Sierra and BIB 95s will work in a 10-twist. Bore dimensions can also have an effect. We’ve found the Lapua 105s, which are “skinnier” than Berger or Sierra 105s, often prefer bores which run on the “tight” side. But still, here are some proven loads that should get you shooting bugholes.


WARNING: With all loads, ALWAYS START 10% LOW and work up incrementally.

Bullet Mfg Grains Powder Primer FPS Comments
80gr FB Berger/Fowler 30.0 VV N135 Fed 205m 3150 Outstanding accuracy in 1:12″ or faster twist. Start .015″ into lands. Great 200/300m load.
88gr FB LoDrag Berger 31.0 Varget CCI BR4 3100 A bit finicky to tune–depth sensitive, but can be super accurate. Good in Dasher too.
90gr Scenar Lapua 33.0 (moly) VV N540 CCI BR4 3050 Very uniform bullet, works in or out of lands. Superb “short-line” bullet for Cross-course.
95gr FB BIB 30.7 Varget CCI 450 2980 Like a laser in a true 10-twist or faster. Quarter-MOA at 200m. Keep ’em under 3100 fps.
95gr VLD Berger 31.0 Varget CCI BR4 3000 Great combo of speed, BC, and accuracy, but can be finicky. Sort bullets by bearing surface and jam ’em.
95gr VLD Berger 31.3 Varget CCI 450 3060 Jammed .012″ in lands this shot in the ONEs in a PacNor 0.236 3-groove. 150 fps faster than Berger 108s.
103gr BT Spencer 30.5 RL 15 CCI 450 2920+ NEW shorter boattail design. JLK Jackets. Tight meplats. Very uniform. Good choice for 1K.
105gr
A-Max Hornady 29.0 H4895 CCI BR4 2840 H4895 is very accurate, low ES/SD. Kyle Brown used a hotter version of this load to set his 1K record group.
105gr
BT Match Berger 29.5 H4895 CCI BR4 2880 J. Schmidt’s recommended “moderate” accuracy load for factory actions. Very accurate and consistent. 1/4 MOA 25-shot Agg at 200.
105gr Scenar Lapua 30.3 Norma 203B CCI BR4 2901 Very Accurate. Extremely low ES=7/SD=3 at .012″ in lands. Powder IS Temp sensitive. 30.5 also very accurate with .020″ jam. BUT may be hot. Start low (29.5gr) with 203B.
105gr Scenar Lapua 30.3 Varget CCI 450 2920+ Very uniform bullet that likes tight bores or canted lands. You can hot up this load in winter by .3 grains. Match load, .015″ into lands.
105gr Scenar Lapua 30.5+ VV N150 CCI BR4 2950+ In a BAT action, Jackie Schmidt runs the Scenars close to 3K with N150. Super accurate in a .236-land Krieger. Work up carefully.
105gr VLD Berger 31.5 IMR 4007ssc CCI 450 n/a With VLDs jammed .015 this shows very tight vertical at 200. 100% load density.
105gr VLD Berger 30.4 VV N540 CCI 450 2900+ Terry Brady has set world records with moly version of this load (31.0 gr), and RL15 works too. Great bullets. High BC.
106gr BT Clinch River 30.4 RL 15 CCI 450 2920 Jason’s World Open-winning bullet/powder. The CR 106s are superb. Ultra-accurate with minimal vertical. There is a higher node too.
107gr BT Sierra 30.0 Varget Fed 205m 2885 Classic accuracy load for the 107 SMKs. Works well in many guns. You can hot it up, but start at 30.0. Try Wolf (Russian) primers too.
108gr BT Berger 30.5 Varget CCI BR4 2900+ NEW bullet. This load has
